Back in L.A. after spending time in the Big Apple with Jared Followill, Ashley Greene stopped into Trousdale Lounge with a group of friends after dining at Boa Steakhouse. Greene mostly hung out with a girlfriend, while the guys in her group acted like bodyguards. Though Ashley wasn't in full-on party mode – she wasn't dancing or being silly – she was laughing and chatting with her friends, an onlooker says.

Costars on True Blood and in real life, Anna Paquin and hubby Stephen Moyer shared a relaxed – and romantic – steak and shrimp dinner at Boa Steakhouse in Santa Monica. "They were really sweet with each, taking turns and trying both entrees," an onlooker says. Adds the onlooker: "When they weren't eating, they were holding hands and leaning into each other and talking."

Jessica Simpson arrived at Trousdale Lounge in L.A. on the arm of her fiancé Eric Johnson after dining together at Boa Steakhouse. Once inside, the happy duo made a beeline to the table where Simpson's BFF Cacee Cobb awaited. It was Cobb's birthday, so everybody was in a celebratory mood, and the happy couple waited for their waitress to pour them drinks. Simpson and Johnson were very affectionate at their table, constantly finding ways to touch each other. The group also toasted with champagne and serenaded Cobb with "Happy Birthday." Simpson's spirits were very high, a source says, as she celebrated her friend's birthday with her new man. The couple also stayed until closing, leaving hand-in-hand, just as they arrived.
